Prosecutors say Yoon, who was impeached over a failed 2024 martial law declaration, threatened ‘constitutional order’.

South Korean prosecutors have asked for ousted President Yoon Suk Yeol to face the death penalty over his failed attempt to impose martial law in 2024.
Special prosecutor Cho Eun-suk’s team made the request to the Seoul Central District Court during court on Tuesday, accusing Yoon of threatening the “liberal democratic constitutional order” with his “self-coup”.
“The greatest victims of the insurrection in this case are the people of this country,” said the prosecutors. “There are no mitigating circumstances to be considered in sentencing, and instead, a severe punishment must be imposed.”
Yoon plunged South Korea into a crisis with his martial law declaration in December 2024, prompting protesters and lawmakers to swarm parliament to force a vote against the measure.
The decree was quickly declared unconstitutional by the Supreme Court, and Yoon was subsequently impeached, removed from office and jailed.
Yoon’s criminal trial for insurrection, abuse of power, and other offences linked to the martial declaration ended on Tuesday after 11 hours of proceedings.
The court is expected to deliver a verdict on the case on February 19, according to the Yonhap news agency.
Yoon says investigations ‘frenzied’
The former president has denied the charges against him, arguing that he was acting within his authority to declare martial law in response to what he described as opposition parties’ obstruction of government.
Speaking in court Tuesday, Yoon criticised investigations into the rebellion charges as “frenzied” and mired in “manipulation” and “distortion.”
If found guilty, Yoon will become the third South Korean president convicted of insurrection, following two ex-military leaders convicted over their roles in the 1979 coup.
But even if Yoon is handed a death sentence, it is unlikely to be implemented, as South Korea has observed an unofficial moratorium on executions since 1997.
Yoon also faces several other trials over various criminal charges related to the martial law attempt and other scandals during his time in office.
A Seoul court is expected to deliver a verdict on Friday on an obstruction of justice case, which could see Yoon facing 10 years in prison.
And he faces a trial on charges of aiding the enemy over allegations he ordered drone flights over North Korea to justify his martial law declaration.
The office of President Lee Jae Myung, who was elected after Yoon was removed from office, said in a statement that it “believes the judiciary will rule … in accordance with the law, principles, and public standards.”
